Katrin,

Hmm... maybe I'll be writing a fact page to go on our web-site until we
get this straightened out.

1)  The models at sourceforge are primarily used only for research.  No
commercial usage.
2)  Most of the corpus are heavily copyrighted and exclude all
commercial usage.  Mostly because they are fully copyrighted texts and
are treated as most books are...

3)  Both these out of the way, our team is also attempting to put
together a way for us to generate and get a free corpus based on other
free sources.  Where the copyright is more of a free information
exchange.  I think WikiNews has been looked at as well as other
sources.  We have a sample server applet that will eventually run on a
server to allow us to mark/tag/take apart the information and generate
the correct format for the training data required for the namefinder,
tokenizer and POS tagger.
      Help on this is extremely welcome and I think you and anyone else
interested can contact Jorn to get started or how to help.
